Héðinsdalsjökull, northern Iceland: geomorphology recording the recent complex evolution of a glacier

Journal of Maps, 2021
The objective of this work is to conduct a detailed mapping of the Héðinsdalsjökull foreland, northern Iceland (65°39′N, 18°55′W). This cirque currently shows a variety of glacial and periglacial landforms derived from a complex deglaciation. Mapping was

Cognitively plausible representations for the alignment of sketch and geo-referenced maps

Journal of Spatial Information Science, 2017
In many geo-spatial applications, freehand sketch maps are considered as an intuitive way to collect user-generated spatial information. The task of automatically mapping information from such hand-drawn sketch maps to geo-referenced maps is known as the

Autonomous exploration using UWB and LiDAR

Journal of Automation and Intelligence, 2023
In autonomous exploration, a robot navigates itself in an unknown environment while building a 2D map of the environment. This is typically done using a LiDAR sensor, which however is susceptible to error accumulation.
